It may be worth while to point out that the dolicho-blond type of European man seems to owe much of its dominating influence and its masterful position in the recent culture to its possessing the characteristics of predatory man in an exceptional degree. These spiritual traits, together with a large endowment of physical energy -- itself probably a result of selection between groups and between lines of descent -- chiefly go to place any ethnic element in the position of a leisure or master class, especially during the earlier phases of the development of the institution of a leisure class. This need not mean that precisely the same complement of aptitudes in any individual would insure him an eminent personal success. Under the competitive regime, the conditions of success for the individual are not necessarily the same as those for a class. The success of a class or party presumes a strong element of clannishness, or loyalty to a chief, or adherence to a tenet; whereas the competitive individual can best achieve his ends if he combines the barbarian's energy, initiative, self-seeking and disingenuousness with the savage's lack of loyalty or clannishness. It may be remarked by the way, that the men who have scored a brilliant (Napoleonic) success on the basis of an impartial self-seeking and absence of scruple, have not uncommonly shown more of the physical characteristics of the brachycephalic-brunette than of the dolicho-blond. The greater proportion of moderately successful individuals, in a self-seeking way, however, seem, in physique, to belong to the last-named ethnic element.
The temperament induced by the predatory habit of life makes for the survival and fullness of life of the individual under a regime of emulation; at the same time it makes for the survival and success of the group if the group's life as a collectivity is also predominantly a life of hostile competition with other groups. But the evolution of economic life in the industrially more mature communities has now begun to take such a turn that the interest of the community no longer coincides with the emulative interests of the individual. In their corporate capacity, these advanced industrial communities are ceasing to be competitors for the means of life or for the right to live -- except in so far as the predatory propensities of their ruling classes keep up the tradition of war and rapine. These communities are no longer hostile to one another by force of circumstances, other than the circumstances of tradition and temperament. Their material interests -- apart, possibly, from the interests of the collective good fame -- are not only no longer incompatible, but the success of any one of the communities unquestionably furthers the fullness of life of any other community in the group, for the present and for an incalculable time to come. No one of them any longer has any material interest in getting the better of any other. The same is not true in the same degree as regards individuals and their relations to one another.
